Application October 5, 1935, Serial No. 443,733 a claims. (or iii-60)This invention relates in general to cordage atives sucli as celluloseesters, cellulose ethers, nnd in am to an improved decorativetycellulose oxy-ethers; gelatine; casein, and other inn cord and tocorrelated improvements in the synthetic plastics. These materials maybe colmethod of producing the same. cred or uncclored, transparent oropaque.

If de- 10character of the cord is seriously impaired. ,Fursired, the non-fibrousmaterial may be plasticized lo then-more, when one of the strands of thecord with any suitable plasticizer such as is known consists of a stripoi tinsel, the sharp edges of in the art, with the object of stillfurther increasthe tinsel strip tend to cut into the fibrous strands,ingthe flexibility of the cord, producingaroughened surface and weakenintthe The metallic strand which is spirally wound is strength oi the cordat such points. about the core may comprise a metal wire or a iii litis, therefore. the principal object of the presnarrow strip of metalsuch as is commonly called ent invention to provide an improveddecorative tinsel". The tinsel is formed preferably by fiattying cord inwhich certain elements art so comtoning a fine metal wire, since thismethod gives blood as to resist disintegration when severed a striphaving rounded edges and avoids the M d, at the e time, to cflerauniform tensile sharp edges produced by cutting a sheet of thin onstrength which cannot be impaired by bending or metal into narrowstrips. In another embodiment t. the metallic strand comprises a narrowstrip of it is a, specific object of the invention to-proflexiblematerial covered on one or both sides with vide a tying cord ofdecorative character formed a metallic coating, such, for example, as astrip oi a core of flexible, non-fibrous material and a of transparentcellulose having on one side a mean decorative element encircling thecore without detallic coating formed by cathode sputtering of iormi orweakening the core. a metal. The metallic strand preferably contrasts@ther objects oi the invention will in part be in color with the coreabout which it is wound obvious and will in part appear hereinafter. andmay be embossed, crinkled, creped or otherw According to the invention,a tying cord is wise surface roughened so as to reflect light from to edofa twisted strip of flexible, non-fibrous a. multiplicity of facets andthus enhance the material about which a relatively flat, thin stranddecorative efiect. For example, the metallic having a metallicappearance, preferably a metal strand 2 may be embossed with a pluralityof strip having rounded edges, is spirally wound in raised points 3 asshown in Fig. 1.

Since certain modifications in the article of the invention may be madewithout departing from its scope, it is intended that all mattercontained in the above description shall be interpreted as illustrativeand not in a limiting sense.

I claim:

1. A decorative tying cord comprising a cord formed of a twisted stripof colored, flexible, nonfibrous regenerated cellulose and a flat, thinmetallic strand wound about said core in open spirals.

2. A decorative tying cord comprising a core formed of a twisted stripof colored, plasticized, non-fibrous material and a flat, thin metallicstrand spirally wound about said core in the'same direction as thedirection in which the core is twisted.

3. A decorative tying cord comprising a core formed of a twisted stripofflexible, non-fibrous material and a strand spirally wound about saidcore, said strand comprising a narrow strip of flexible material havinga metallic coating.

4. A decorative tying cord comprising a core formed of a twisted stripof flexible, non-fibrous material and a strand spirally wound about saidcore, said strand comprising a strip of transparent, flexible,cellulosic material having a metallic coating.

5. Adecorative tying cord comprising a core formed of a twisted strip offlexible, non-fibrous material and a strand spirally wound about saidcore, said strand comprising a flat, thin strip 01' tinsel havingrounded edges.

6. A decorative tying cord comprising a core formed of a twisted stripof flexible, non-fibrous material and a strand spirally wound about saidcore in the same direction as the direction in which the core istwisted, said strand comprising a twisted fiat, thin strip of tinsel.

7. A decorative tying cord comprising a core formed of a twisted stripof flexible, non-fibrous material and a strand spirally wound about saidcore in open coils, said strand comprising an embossed flat, thin stripof tinsel.

8. A decorative tying cord comprising a core formed of a twisted stripof flexible, non-fibrous material and a flat, thin metallic strandspirally wound about said core, said strand having a crinkled surface.
